Example

[0018]With reference to the drawings and in particular to FIG. 1 to FIG. 4, a structure of a first embodiment of a tire temperature and a tire pressure wireless sensing device is shown. The tire temperature and tire pressure wireless sensing device is engaged with an air-intake mouth of the wheel to sense gas temperature and pressure inside the wheel to obtain the usage condition of the tire to increase the drive safety. The tire temperature and tire pressure wireless sensing device includes a housing 10, a valve body 20, a power supply module 30, a circuit board 40 and a transmission antenna 50.

[0019]The housing 10 is engaged with the air-intake mouth (not shown), which includes a fixed seat 11, a bottom seat 12 with a first recess 122 and a cap 13 with a second recess 131. The fixed seat 11 is made by plastic injection molding. The bottom side of the fixed seat 11 includes a circular sidewall and the circular sidewall is engaged with the bottom seat 12 to form an air chamber 15. I...

Abstract

A tire temperature and tire pressure wireless sensing device is provided, which includes a housing, a valve body, a power supply module, a circuit board and a transmission antenna. The power supply module is disposed on the fixed seat of the housing, and the circuit board includes a wireless transmission module and a sensing module thereon. The sensing module is disposed corresponding to an air-intake through hole of the bottom seat of the housing. The valve body is engaged with the air-intake through hole and one end of the transmission antenna is disposed in an antenna slot.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a tire temperature and tire pressure sensing device, and in particular to a tire temperature and tire pressure sensing device for detecting the instant and accurate gas temperature and gas pressure, emitting the effective wireless signal and preventing the signal attenuation and is suitable for an air-intake mouth of all kinds of wheel.BACKGROUND OF THE INVENTION[0002]The conventional tire temperature and tire pressure wireless sensing device includes an air-intake device, a bidirectional sleeves and a cap. The air-intake device includes an in-take seat. One end of the intake seat is connected with an intake mouth of wheel. The bidirectional sleeves include a separation part, in which a first connection part and a second connection part are disposed two opposite ends of the separation part respectively. The first connection part is engaged with another end of the air-intake seat to form an air chamber which used to accommo...
